FLAC 1.1.4 is released; see the download page and latest comparison. The windows installer for 1.1.4 is not ready yet but should be along soon. If needed you can replace the binaries from the current (1.1.3) installer with the ones in the 1.1.4 .zip on sourceforge.

The main features of this release:

Compression improvements in all modes (-0 .. -8) with no change to the format or decrease in speed

Speed increases for all modes, both encoding and decoding. Encoding at -8 is twice as fast as in 1.1.3
